POLY NORM AR TORSIONALLY FLEXIBLE KTR

DESCRIPTION: POLY-NORM® shaft couplings are characterized by a compact design. The torque is transmitted via elastomers between the cams also serving to offset displacements and dampen shocks and torsional vibrations.

Shaft coupling POLY-NORM AR KTR

Compact and low-priced standard version
The torsionally flexible, fail-safe shaft coupling POLY-NORM AR is a compact two-part shaft coupling for torsional vibration-damping power transmission.

The hubs made of cast iron identical in design make the standard version POLY-NORM AR specifically low-priced.
For mounting the shaft coupling the hubs are simply pushed onto the shafts and fastened axially by means of setscrews.

Applications of our torsionally flexible, fail-safe shaft coupling Poly Norm AR:

The POLY-NORM AR shaft coupling is used in almost all fields of general engineering, here mainly in the pump industry (pump coupling)."
